GRAIN-SAMPLER.

Application filed May 5, 1917.

To all whom it may concern:

Be it known that I, ARTHUR M. VVISWELL, a citizen of the United States,residing at Wichita, in the county of Sedgwick and State of Kansas, haveinvented new and useful Improvements in Grain-Qamplers, of which thefollowing is a specification.

This invention relates to implements for extracting samples of grainfrom cars, the primary object of the same being to provide a device ofthis character having a valve casing provided with ports and an innercasing provided with ports co-acting therewith, the

arrangement of the ports being such that a minimum amount of movement ofthe inner casing relative to the valve casing is necessary in theoperation of the device, so that the necessary wear is reduced and thenecessity of disassembling the device to remove dirt and chaff, whichtends to clog the same is minimized.

A further object of my invention is to provide a simple and durablemeans for indicating the various operative positions of the inner casingrelative to the valve casing, so that the operator may easily determinethe same while operating the device.

With these and other objects in view which will be hereinafter fullydescribed and particularly pointed .out in the claim, the inventionconsists in the novel construction and arrangement of parts illustratedin the accompanying drawings forming a part of this specification, inwhich Figure 1 is a front elevation of a grain sampler closed,

Fig. 2 is a similar view of the implement open,

Fig. 3 is a cross section on the line A-A of Fig. 1,

Fig. 4 is a cross section on the line B-B of Fig. 2,

Fig. 5 is a partial vertical sectional side elevation of the implementshowing the inner casing positioned to connect the inclosure thereofwith the passage of the chute, as hereinafter described,

Fig. 6 is a cross section on the line C--C of Fig. 5,

Fig. 7 is a partial rear elevation of the outer end of the implement.

Like characters of reference indicate like parts in the various views.

In the drawings 1 designates generally the body of the implement. Thisbody has Specification of Letters Patent.

an outer cylindrical valve casing 3 and a chute member 4 secured on theunderside of the valve casing and extending longitudinally thereof, saidchute member forming a passage 5 on the outside of the valve casing 3.Inlet ports 6 are formed in the valve cas ing 3 and are disposed atregular intervals along the length of the valve casing, said ports lyingopposite the chute member 4:. Outlet ports 7 are formed in the valvecasing 3 and connect the inclosure of the valve casingwith the passage 5each port 7 lying opposite a respective port 6. The body 1 has a pointedend 8, which allows the implement to be easily introduced into a bin ofgrain. An inner casing 9 is provided which is adapted to closely fitwithin the inclosure of the outer casing. Partitions 10 are securedwithin the inclosure of the inner casing and divide said inclosure intoa series of separate compartments. Inlet ports 11 are disposed atintervals along the inner casing and communicate with respectivecompartments of the inner casing. The ports 11 are adapted to registerwith respective ports 6 when the inner casing assumes a certain positionrespective the outer casing, as hereinafter described. Outlet ports 12are formed in the inner casing and communicate with respectivecompartments thereof, and are adapted to register with respective ports7 when the inner casing assumes another position respecting the outercasing, as hereinafter described. The various ports of the inner casingare so disposed relative to the respective outlet ports thereof that theportion of the wall of said inner casing which lies between two opposingsides of said ports is just wide enough to cover the inlet ports of thevalve casing, and the inlet ports of the valve casing are so disposedrelative to the respective outlet ports thereof that the portion of thewall of said valve casing whichlies between two of the opposing sides ofsaid ports is just wide enough to cover either set of ports in saidinner casing whereby the inner casing need only be rotated the width ofsaid inlet ports to effect the closing of the inlet ports and theopening of the outlet ports, see Fig. 4, and to double the width of saidinlet port to effect the closing of both inlet and outlet ports of thevalve casing.

A flange 13 is formed upon the outer surface of the valve casing 3adjacent the open upon the flange 13 and are adapted to be engaged bythe respective ends of the cleat 14; to enable the operator to ascertainthe rela tive positions of the valve casing 3 and the inner casing 9when the implement is inserted in a bin of grain.

lVhen the inner casing is positioned so that the inlet ports 11 thereofregister with the inlet ports (3 of the valve casing the outlet ports ofthe inner casing are out of registry with the outlet ports 7 of thevalve casing, and when the outlet ports 12 of the inner casing are inregistry with the outlet ports 7 of the valve casing the inlet ports 11of the inner casing are out of registry withtthe inlet ports 6 of thevalve casing. When the inlet ports 11 are in registry with the. inletports 6 the cleat 14s is positioned at a point intermediate theshoulders 16, 17. A hole 18 isformed in the cleat is just above theflange 13, and a depression 19 is formed in the flange 13 and registerswith the hole 18 when said inlet ports 11 are in registry with the inletports 6. A ball 20 lies in the hole 8 and a spring plate 21 has its oneend secured to the cleat Li and has its other end overlying the saidhole 8 to normally hold said ball 20 a ainst the flange 13 and to pressthe sane into the depression 19 when said hole and said depression arein registry.

Fig. 6. By means of the above described n'ieehanism the operator maydetermine when the inlet ports 11 are in registry with the inlet ports6. See Fig. 4. When the inner casing is rotated to the left from thisposition until the cleat 1% engages the shoulder 16 the inlet ports 11are out of registry with the inl t ports 6, and the outletports 12 arein registry with the outlet ports 7 to discharge grain in thecompartients of said inner casing into'the passage 5 of the chute e fromwhich the grain may be drawn through the open end of said chute 4:adjacent the handle 13. When the inner casing is rotated to the rightand the cleat 14C engages the shoulder 17 the ports 11 are out ofregistry with the ports 6, and the ports 12 are out of registry with'the ports 7. See Fig. 3. In this position grain may be confined withinthe compartments of the inner casing, so that samples of the grain atdifferent depths may be carried about in the implement, and at any timewhen a .mean sample is desired-the inner casing may be rotated to theleft until the cleat 14 engages the shoulders 16 when the grain in thecompartments of the inner casing may be discharged through the chutemember 4.

Having thus fully described my invention, I claim A grain samplercomprising a valve casing having inlet and outlet ports formed therein,aninner casing mounted for rotation in said valve casing and havingrespective ports therein adapted to register with respective inlet andoutlet ports of said valve casing when in different positions relativeto said valve casing, a flange on said valve casing, having a depressiontherein, oppositely disposed shoulders on said flange, a cleat mountedon said inner casing and engaging said flange between said shoulders andhaving a hole therein adapted to register with said depression when saidcleat is positioned intermediate said shoulders, a ball in said hole anda springengaging said ball and serving to move said ball into saiddepression when said hole and depression are in registry, said shouldersand said depression being so disposed as to indicate the variousoperative positions of said inner casing relative to the valve casing.

In testimony whereof I affix my signature.

ARTHUR M. -WIS'WELL.
